not exactly.

air in may be the same, but fuel usage is way up. You burn it, it turns into something mass wise. Gotta go out the exhaust.

We always get more power with E85 then gasoline, and less backpressure.
Tested several times..

Right, but it is also cooler, so velocity wouldn't be as high as the same amount of gasoline burned, so it wouldn't exactly be a 30% difference in exhaust requirements, but I could understand there being a difference.

This wouldn't impact the requirements for the cold side of the turbo in any way though, right?

No the compressor side requirements can stay the same, but just the exhaust side needs to be compensated for.

My statement about fuel volume being irrelevant was directly related only to the compressor side, which Drturbo states would stay the same.

I caught on after a while. I was talking Turbine.

interesting, now Houston needs to have more E85 stations so I can convert.
